Computer modeling through digital range images has been used for many applications, including 3D modeling of objects belonging to our cultural heritage. The scales involved range from small objects (e.g. pottery), to middle-sized works of art (statues, architectural decorations), up to very large structures (architectural and archaeological monuments). For(More)
This article reports on a multi-resolution and multi-sensor approach developed for the accurate and detailed 3D modeling of the entire Roman Forum in Pompei, Italy.The archaeological area, approximately 150 × 80 m, contains more than 350 finds spread all over the forum as well as larger mural structures of previous buildings and temples.The(More)
The article describes a multi-resolution approach developed for the 3D modeling of the entire Roman Forum in Pompeii, Italy. The archaeological area, approximately 150 x 80 m, contains more than 350 finds spread all over the Forum as well as larger mural structures of previous buildings and temples. The interdisciplinary 3D modeling work consists of a(More)
This paper describes 3D acquisition and modeling of the "Plastico di Roma antica", a large plaster-of-Paris model of imperial Rome (16/spl times/17 meters) created in the last century. Its overall size demands an acquisition approach typical of large structures, but it is also characterized by extremely tiny details, typical of small objects: houses are a(More)
In the first months of 2011, Internet communications were disrupted in several North African countries in response to civilian protests and threats of civil war. In this paper we analyze episodes of these disruptions in two countries: Egypt and Libya. Our analysis relies on multiple sources of large-scale data already available to academic researchers: BGP(More)
The performance of 2D digital imaging systems depends on several factors related with both optical and electronic processing. These concepts have originated standards, which have been conceived for photographic equipment and bi-dimensional scanning systems, and which have been aimed at estimating different parameters such as resolution, noise or dynamic(More)
While 3D imaging systems are widely available and used, clear statements about the possible influence of material properties over the acquired geometrical data are still rather few. In particular a material very often used in Cultural Heritage is marble, known to give geometrical errors with range sensor technologies and whose entity reported in the(More)
— The traditional approach for understanding an archaeological site, mainly focused on excavations and stratigraphic examination of findings through the archaeological analysis, is still the main way for hypothesizing its most probable interpretation. As demonstrated in several case studies 3D digital acquisition techniques may greatly help for applications(More)
